Techopedia Explains Cold Boot

A cold boot is usually set in motion by pressing a computer’s power button. A computer doing a cold boot is already in a shutdown state, wherein no hardware, software, network or peripheral operations are occurring. For the most part, a cold boot is done so that a computer is able to perform standard computing tasks (general use). However, sometimes cold boot is necessary after software and usually hardware troubleshooting.

For example, unlike a warm boot, cold boot flushes not only RAM contents but also clears the caches. This ensures that no traces or instances of conflicting programs or their data are left within the computer memory.
